An immigration solicitor will usually begin with a consultation to understand your circumstances, immigration history and goals. They should explain the relevant route, eligibility requirements, likely costs and documents needed, then confirm their terms of business before acting. They may help prepare forms and evidence, check your application and submit it to the Home Office. The solicitor can also update you about requests for further information or biometric appointments, although they cannot control processing times or guarantee an outcome. Check that the solicitor is regulated by the SRA, and use GOV.UK for current official requirements.
